Two Secret Service agents have been removed from President Obama's detail and are under investigation for alleged sexual misconduct, according to a Washington Post report.

The paper reports that two senior supervisors at the agency, Ignacio Zamora, Jr., and Timothy Barraclough, were found to have sent sexually suggestive emails to a female subordinate. The emails came to light as part of an investigation into an incident in May in which Zamora was found attempting to force his way into a woman's room at the Hay-Adams Hotel in Washington to retrieve a bullet from his service weapon.

Zamora has been pulled from his position as a shift supervisor for the president's protective division, while Barraclough has been moved to a separate part of the division.

The latest allegations of misconduct come as the agency is preparing for the release of an inspector general report into a prostitution scandal at last year's Summit of the Americas in Cartagena, Colombia. 12 Secret Service agents were implicated in the scandal, nine of whom have since left the agency through resignation, dismissal or retirement.

In the wake of the incident, the Secret Service issued new rules regulating the consumption of alcohol by agents, including banning drinking 10 or fewer hours before reporting to work.

Secret Service spokesman Ed Donovan referred to the incidents investigated by the Post as "isolated incidents of misconduct" in a statement to the paper.
